During the Peasants' Revolt of 1381, strong clashes led to attacks and looting of university properties as locals contested the privileges granted by the British government to the University of Cambridge's academic staff. Residents burned university property in Market Square to the famed rallying cry "Away with the learning of clerks, away with it!". Following these events, the University of Cambridge's Chancellor was given special powers allowing him to prosecute criminals and reestablish order in the city.

The university also has proven a source of extraordinary growth in high tech and biotech start-ups and established companies and associated providers of services to these companies. The economic growth associated with the university's high tech and biotech growth has been labeled the Cambridge Phenomenon, and has included the addition of 1,500 new companies and as many as 40,000 new jobs added between 1960 and 2010, mostly at Silicon Fen, a business cluster launched by the university in the late 20th century.
